How long should the size-up be performed?

• A. Only at the start
• B. Only during extrication
• C. Continuously until end of call/incident
• D. After patient extraction

Answer: (C)

Size-up should be continuous from arrival through the end of the incident. In an auto crash, conditions on the scene can change in moments—new hazards can appear as the vehicle is stabilized, as the patient is accessed, or as tools are used. Fuel leaks, shifting vehicle mass, unstable debris, airbags, downed power lines, weather, traffic, and bystander activity are all variables that can evolve. By continually reassessing, you keep safety as the top priority, tailor the plan to current risks, and choose the right approach, tools, and timing for every step of the operation. If you size-up only at the start, you risk missing an emerging hazard; if you limit it to during extrication, you might ignore changes before or after you begin; if you wait until after extraction, hazards could still threaten crew and patient during the process. Continuous size-up ensures decisions stay appropriate and safe through the entire call.
